CONTROL OF EXHAUST EMISSIONS OF JATROPHA OIL IN CRUDE FORM AND BIODIESEL FROM HIGH GRADE LOW HEAT REJECTION DIESEL ENGINE

Aim: Investigations were carried out to control the exhaust emissions of smoke levels and NOx emissions from a high grade low heat rejection (LHR) diesel engine consisting of air gap insulated piston with 3-mm air gap, with superni (an alloy of nickel) crown, air gap insulated liner with superni insert and ceramic coated cylinder head with different operating conditions of crude jatropha oil (CJO) and biodiesel with varied injection timing and injection pressure with selective catalytic reduction technique.
